Optical design with 7mm pitch woofer - (180 arcsec FOV, still 2-tier)
November 20, 2007
Optical design for 150 arcsec field - (back to 5mm pitch, 2-tier, but smaller field (150 arcsec))
This is Brian's design with a little bigger K-mirror to accomodate 150 instead of 120 arcseconds.

1-tier, 7mm pitch, 150 arcsecond field AO relay design
This is an exploration of the idea of putting it all on one-tier, with a "big" (7mm pitch) woofer DM.
NOTE These have an error in one of the path lengths (tweeter to 4th OAP)
November 27, 2007, CORRECTED 1-tier, 7mm pitch, 150 arcsecond field AO relay design
This is an exploration of the idea of putting it all on one-tier, with a "big" (7mm pitch) woofer DM. Previous error is corrected.

Peter's Zemax file: Additional ideas for the 1-tier layout with multiple configurations
Peter's ppt summary of this optical design:
NGAO 1-tier optical relay.ppt
Anna's Zemax file: Combined Reni's 140mm 1-tier zemax with Peter's original 1-tier Keck AO system
Changes made were OAP specifications, added LGS WFS dichroic, DM angle reduced to 7deg, OSM beamsplitter angle reduced to 10.5deg.
This file is not complete! For use tomorrow.
Reni's 2-tier, folded 2nd relay design, based on Brian's original 2-tier design but with the 2nd relay folded rather than transmitted by a dichroic (this is Peter's idea from the 1-tier layout). Also a powerpoint slide showing the possible configuration of various NGAO components.
